Lower-Luminosity Obscured AGN Host Galaxies are Not Predominantly in Major-Merging Systems at Cosmic Noon
Erini Lambrides, Marco Chiaberge, Timothy Heckman +15
For over 60 years, the scientific community has studied actively growing central super-massive black holes (active galactic nuclei -- AGN) but fundamental questions on their genesi…
The most luminous blue quasars at 3.0<z<3.3. II. CIV/X-ray emission and accretion disc physics
Elisabeta Lusso, Emanuele Nardini, Susanna Bisogni +12
We analyse the properties of the CIV broad emission line in connection with the X-ray emission of 30 bright SDSS quasars at z~3.0-3.3 with pointed XMM-Newton observations, which we…
The XMM-SERVS survey: XMM-Newton point-source catalogs for the W-CDF-S and ELAIS-S1 fields
Q. Ni, W. N. Brandt, C. -T. Chen +30
We present the X-ray point-source catalogs in two of the XMM-Spitzer Extragalactic Representative Volume Survey (XMM-SERVS) fields, W-CDF-S (4.6 deg) and ELAIS-S1 (3.2 deg)…
The G-dwarf distribution in star-forming galaxies: a tug-of-war between infall and outflow
E. Spitoni, F. Calura, V. Silva Aguirre +1
In the past, the cumulative metallicity distribution function (CMDF) turned out as a useful tool to constrain the accretion history of various components of the Milky Way. In this…
Chandra and Magellan/FIRE follow-up observations of PSO167-13: an X-ray weak QSO at
Fabio Vito, William Nielsen Brandt, Federica Ricci +19
The discovery of hundreds of QSOs in the first Gyr of the Universe powered by already grown SMBHs challenges our knowledge of SMBH formation. In particular, investigations of …
Systematic search for lensed X-ray sources in the CLASH fields
Ang Liu, Paolo Tozzi, Piero Rosati +8
We search for unresolved X-ray emission from lensed sources in the FOV of 11 CLASH clusters with Chandra data. We consider the solid angle in the lens plane corresponding to a magn…
